Patent GB-889328-A (GB)
Title: Apparatus for measuring small direct voltages
IPC: G01R19/00
Filed: 1958-05-02
Abstract: 889,328. Voltage measuring. NEDERLANDSCHE INSTRUMENTEN-EN ELECTRISCHE APPARATEN FABRIEK N.V. May 2, 1958 [May 6, 1957], No. 14145/58. Class 37. In apparatus for measuring the voltage of a source T having a large internal resistance, such as a thermocouple, a millivoltmeter M is connected across the source, and a compensating voltage of the same polarity as the source is connected through resistor R to the meter M, a potentiometer P enabling this voltage to be adjusted to a predetermined value, the adjustment being made with T disconnected from M. The magnitude of the compensating voltage, when T is connected to M, will be less than the predetermined value owing to an increase in the volts drop across resistor R arriving from the current flow through T from the compensating source. When the voltage developed by T increases to the predetermined value, no current flows through T from the compensating supply, and the compensating voltage applied to M rises to the predetermined value, the volts drop across R decreasing accordingly. The meter M thus indicates when the source voltage reaches a predetermined value, this indication being unaffected by the high internal resistance of T. An adjustable contact O set to the predetermined value of the voltage may be provided, whereby when the source voltage reaches this value, a contact on the pointer W engages O for signalling or regulating purposes.

[Also in Division B8] A coffee making device comprises a sealed two compartmented pack made of heat resisting material, containing ground coffee in one compartment and with a filter between the compartments. In the form shown (Fig. 1) water is passed into the compartment 6 through a cut-out in the right hand corner and the opening resealed with a clamp 16. A similar cut-out 15 in the compartment 4 is left open. On heating the water, it rises into the compartment 6. This process may be repeated fuses the coffee 5 and is then allowed to fall back through the filter 8 into the compartment6. This process may be repeated until the coffee is sufficiently infused when it is removed by cutting a seal 2. The filter may be formed by seaming, a pattern of seals or embossed material. Alternatively it may be a separate portion held in position by seams. The devices may be joined along their longitudinal walls to form a strip (Fig. 5, not shown). In another embodiment (Fig. 10, not shown) the compartment may be wholly above the compartment and after removal of a seal (66), a skirt portion (65) is folded back over the mouth of a container holding water (Fig. 12, not shown). Alternatively the skirt portion may be omitted and the lower compartment placed in the container. Boiling water may be poured directly into the compartment containing the coffee in which case a finer filter is used. The device is preferably made of plastics or aluminium foil.

Abstract: 528,870. Uniting by fusion. UNA WELDING, Inc. May 16, 1939, Nos. 14595 and 14596. Convention dates, July 25, 1938, and March 29, 1939. [Class 83 (iv)] A flux carrying tape which is to be disposed round an arc-welding wire consists of a mesh strip having longitudinal and transverse elements, the latter being substantially permanently deformable so as to render the tape self-retaining of its shape when disposed about the wire. The mesh strip A, which carries flux 10 may consist of longitudinal threads 11 of cotton, asbestos fibre, finely spun glass &c. and transverse soft annealed wires 12 which preferably form a woven fabric. The wires, which may provide alloying or de-oxidizing material, may be formed of copper, iron, stainless steel, of the alloy sold under the Registered Trade Mark "Monel" metal, or alloys or other inelastic deformable material. The tape thus maintains its folded position and does not char nor tend to shrink in width. The, transverse wires may be in the form of a continuous thread extending back and forth through the longitudinal threads in parallel or sinuous formation. The mesh strip may be of double width so that it may be folded on itself, Fig. 4, or two tapes of normal width may be superposed. One thickness may be of the character stated and the other thickness may have warps and weft both of cotton. The tape may be applied to the welding wire 15 during feeding of the wire by rolls 21 to the work. The wire passes through straightening rolls 22 and has current supplied thereto by brushes 23. The tape passes from a reel 16 through smoothing rolls 17 and over a roll 19 on to the grooved roll 20 to form it into arcuate shape. It then passes through a conical passage 24 in a member 25 to bring the edges of the tape together, and then passes through a deeply grooved roll 26 into which it is pressed by a shallow grooved roll 27 under control of a spring 30.

Abstract: 769,774. Electric indicating systems. DAIMLER-BENZ AKT.-GES. May 24, 1955 [May 24, 1954], No. 14964/55. Class 40 (1). [Also in Group XXXVI] An A.C. energized bridge measuring apparatus comprises an inductance in one or two adjacent arms thereof responsive, e.g. to mechanical displacement, rebalancing resistance arms completing the bridge, an indicating device responsive to the magnitude and phase sense of the unbalance, and switches enabling either or both inductances together with series variable compensating resistances to be alternatively connected into a resistance-measuring bridge whereby temperature variations of resistance of the inductance arms may be measured and re-adjusted to a standard value. In Fig. 1, a Wheatstone bridge B for measuring displacements, e.g. the valve clearances of an I.C. engine, comprises calibration arms b, b1 having either interchangeable fixed resistances or variable balancing resistances w, w1, and adjacent measuring arms a, al containing variable temperature compensating resistances w2, w3 and displacement sensitive inductance coils s, sl wound on a brass bobbin g (Fig. 2), and individually surrounded by soft iron armature members e, h. Their inductances are reciprocally variable by a displacement responsive double-core comprising soft iron portions longitudinally separated by a non- magnetic portion i; the inductances being equal when the latter is symmetrically disposed within both coils. The bridge B is excited from an A.C. source G, and the unbalance output d is compared with the excitation c in a demodulator (not shown) having an indicating instrument (e.g. an oscillograph) showing the magnitude and phase of the unbalance, either directly representing the displacement or to permit adjustment of resistances w, w1 for balance as a measure of the displacement. Arms a, a1 also contain switches k, k1 which either complete bridge B for measurement or connect the arms in parallel as a single arm of a D.C. energized auxiliary bridge comprising a standard resistance w4 and an adjustable slide wire p and a galvanometer m, so that at any time during measurement the D.C. resistances of arms a, a1 are determinable and adjustable to a predetermined value by resistances w2, w3 to compensate for temperature variations. Switches k, k1 may be push-button operated and either or both may be ganged with excitation switch o of the auxiliary bridge and with a further switch (not shown) disabling the indicating instrument of the main bridge. A single displacement sensitive coil may be used, and the coils may be wound on formers of zero temperature coefficient (e.g. ceramic) material so that dimensions remain constant.
